Process for treating hair fibres, comprising: (i) combing said fibres, (ii) applying vapour to said fibres, the flow rate of vapour applied being strictly less than 1 g/min, (iii) hair shaping, by heat treatment without vapour, of the hair fibres by conduction and/or by radiation, steps (ii) and (iii) being separate.

A system, computer readable medium and method for selective brightening of hair, the method may include or may be preceded by applying at least one photosensitive material to the hair. The method may also include forming at least one pattern of brightened hair by illuminating the hair by at least one pattern of illumination.

The present invention provides hair straightening compositions comprising acrylic polymers configured to crosslink upon drying and thereby to form a film that is able to preserve hair in straightened conformation. Also provided is a hair straightening cosmetic formulation comprising said hair straightening composition and its use in straightening hair or preserving hair in a straightened conformation. The hair straightening effect is temporary and can be removed when the formulation is washed away in water or with shampoo. The cosmetic formulations of the present invention are ready to use formulations and may be applied frequently.
